BOM

Connect the IR led to the transistor to the Pin 3 of the Arduino following that scheme.

Here the 2N2222 PinOut:

Now connect the switch

The switch is temporary and will be substituted by the Ecobee contacts but for testing purposes is rather easy to implement and proof it’s working.

Code

Upload next code to make it working:

Test your new controller if drive correctly your AC.

Next step is to connect it to the Ecobee thermostat.
See you at next post.

The answer is simple and in the next lines we will figure out how to adapt the 24V AC US Thermostat Standard to 230V European Standard.
